tbh, this also can happen to vids on sites like PH or Xvids, jumping between vids can create a lag in buffering in general...
or stop being a perve and trying to get to the hardcore bit first
joking aside, maybe one of the guys above can help you, hopefully they will! But as said, jumping up and about on a film can create lag on buffering no matter which site, this is what i´ve noticed
